目的：嗅觉-味觉感觉特异性饱腹感在食物摄取的终止中起重要作用。这种机制的缺陷，通过增加食物摄入量，可能是超重发展的一个因素。本研究旨在探讨超重者的感觉特异性饱腹感是否与正常体重者不同。受试者：144名受试者（男女各半;年龄范围：17-62岁; BMI范围：17-39 kg m（-2））。测量：在摄入单一选择的食物之前和之后评估嗅觉愉悦（OP）和味道愉悦（FP）。提供了三个类别的六种食物：黄瓜和番茄，菠萝和香蕉，花生和开心果。根据受试者对其中一种的偏好，将受试者分为六组（每组24名受试者，性别比例相同）。实验顺序为（1）评价6种食物（OP），（2）随意摄入首选食物（FP），（3）第二次评价6种食物（OP）。BMI与享乐参数（OP和FP）或摄入量（数量和体积）之间无显著相关性。摄食前OP和FP与摄食重量（OP：r=0.468; FP：r=0.415; P < 0.01）、体积（OP：r=0.428; FP：r=0.407; P < 0.01）和摄食时间（OP：r=0.184; FP：r=0.343; P < 0.05）相关。OP的下降与摄食量（r=0.271，P < 0.01）和摄食量（r = 0.263，P <0.01）相关，而与摄食持续时间无关。结论：在单一食物摄入后，嗅觉-味觉感觉特异性饱腹感与摄食量和摄食持续时间相关，而与体重无关。这表明，超重和瘦的主题有类似的享乐控制的食物摄入量与简单的食物。
Objective: Olfacto-gustatory sensory-specific satiety plays an important role in the termination of food ingestion. A defect in this mechanism, by increasing food intake, could be a factor in development of overweight. The present study was conducted to explore whether sensory-specific satiety in the overweight may be different from that in normal-weight subjects.Subjects: 144 subjects (half men, half women; age range: 17-62 years; BMI range: 17-39 kg m(-2)).Measurements: Olfactory pleasure (OP) and flavor pleasure (FP) were evaluated before and after ingestion of a single chosen food. Six foods from three classes were offered: cucumber and tomato, pineapple and banana, and peanut and pistachio. According to the subjects' preference for one of them, subjects were classified into six groups (24 subjects each with equal sex ratio). The experimental sequence was (1) evaluation of the six foods (OP), (2) ad libitum intake of the preferred food (FP) and (3) second evaluation of the six foods (OP).Results: Food intake was limited by sensory-specific satiety (that is, a decline in FP for the ingested food) in overweight subjects just as it was in the leanest. There was no significant correlation between BMI and hedonic parameters (OP and FP) or intakes (quantity and volume). Pre-ingestive OP and FP correlated with the ingested food's weight (OP: r=0.468; FP: r=0.415; P < 0.01), volume (OP: r=0.428; FP: r=0.407; P < 0.01) and intake duration (OP: r=0.184; FP: r=0.343; P < 0.05). The decline in OP, but not in FP, correlated with ingested weight (r=0.271, P < 0.01) and volume ( r 0.263, Po0.01) but not with duration.Conclusion: After intake of a single food, olfacto-gustatory sensory-specific satiety correlated with the ingested food's weight and volume and with the duration of ingestion, but not with bodyweight. This suggests that overweight and lean subjects have similar hedonic control of food intake with simple foods.
